Comments:       Compares fsarchiver to partimage
                https://www.fsarchiver.org/partimage/
                I have enabled only lzma & zstd compressors
                To save OR restore partition(s), target partition(s)
                --- best  be unmounted. Considered safe for  
                EXT4, XFS unstable for NTFS.  Below I use the -a switch which 
                claims ignores support for xattr and acl as they will not be preserved. 

                fsarchiver counts partitions in image files from zero.

                My way differs somewhat  to man pages.  $ sudo su
                Use mount tool to mount sda4 (where I write image to)
                Use mount tool to unmount partitions to image/restore
                # cd /mnt/sda4
                 
                To save current partition image for one patition, second line for 2xpartititons
                # fsarchiver savefs 1.fsa /dev/sda1 -a   
                # fsarchiver savefs 2.fsa /dev/sda1 /dev/sda3 -a   
 
                To restore a saved image to an existing partition - over writes all data
                Top line single restore, bottom 2 lines to restore 2 partitions
                # fsarchiver restfs /z/1.fsa id=0,dest=/dev/sda1
               
                # fsarchiver restfs /z/2.fsa id=0,dest=/dev/sda1
                # fsarchiver restfs /z/2.fsa id=1,dest=/dev/sda3

                Please see the man page for examples including splitting, encrypting etc
